Well, that doesn't mean that your OpenGL installation cannot be broken for some
reason...

As mentioned, this bug should not be relevant on x86_64 as GLX is the default
there. (*)

Apparently it would try to fall back to GLES if it cannot load the GLX
libraries, which then results in this error message (see e.g.
https://forums.opensuse.org/showthread.php/528712-Unable-to-open-Kmail-(or-Kontact)
), but if the OpenGL installation is broken then GLES probably wouldn't work
either anyway even if it would find the libraries.

(*) Except on Wayland where only GLES is supported, but we actually patched
QtWebEngine to always use software rendering on Wayland, exactly because of
this.

Starts fine here on x86_64, I tried on a 15.0 KDE LiveCD (X11 session).

Good to hear that it works for you on 15.1, but that doesn't necessarily mean
that the bug is fixed.

Just to be clear: The bug is that libGLESv2.so is loaded from the wrong
directory.
But as explained this should not matter on x86_64 as it should use GLX in the
first place and not GLES.

So it would be nice to have a confirmation on ARM, where GLES is the default I
think.

OTOH, it will likely be difficult to find and backport fixes to 15.0 anyway (I
already spent some time searching but didn't find any seemingly relevant
upstream change).
If this is indeed a general problem on ARM, we probably could force software
rendering on ARM though as we already do for nouveau and Wayland on all
architectures.

I created packages that do this:

@Jogchum Reitsma: maybe you would want to try them?
